After leaving my negatives to dry, I came back to find they were covered in a white/milky residue. I tried to remove it on an unexposed part of the film, and it comes off, but I'm confused as to what caused it. The only thing I did differently this time was use hypo clearing solution after fixing. My process went like this:

1. Develop in HC-110
2. Stop Bath (Kodak Indicator)
3. Fixer (Kodak fixer, the powder stuff).
4. Hypo (Kodak)
5. Wash
6. Another run through Hypo.

Is it residue from hypo? I mean i figure it might be since its a sodium based formula. Please help me if you have any ideas, thanks!
